The Tribe fears that construction of the pipeline, which runs within half a mile of its reservation in North and South Dakota, will destroy sites of cultural and historical significance. It has now filed a Motion for Preliminary Injunction, asserting principally that the Corps flouted its duty to engage in tribal consultations under the National Historic Preservation Act (NHPA) and that irreparable harm will ensue. After digging through a substantial record on an expedited basis, the Court cannot concur. It concludes that the Corps has likely complied with the NHPA and that the Tribe has not shown it will suffer injury that would be prevented by any injunction the Court could issue.

However, shortly after the decision was handed down, the Department of Justice, the Department of the Army and the Department of the Interior issued a joint statement (full text) reading in part:

The Army will not authorize constructing the Dakota Access pipeline on Corps land bordering or under Lake Oahe until it can determine whether it will need to reconsider any of its previous decisions regarding the Lake Oahe site under the National Environmental Policy Act (NEPA) or other federal laws. Therefore, construction of the pipeline on Army Corps land bordering or under Lake Oahe will not go forward at this time. The Army will move expeditiously to make this determination, as everyone involved — including the pipeline company and its workers — deserves a clear and timely resolution. In the interim, we request that the pipeline company voluntarily pause all construction activity within 20 miles east or west of Lake Oahe.

Furthermore, this case has highlighted the need for a serious discussion on whether there should be nationwide reform with respect to considering tribes’ views on these types of infrastructure projects. Therefore, this fall, we will invite tribes to formal, government-to-government consultations on two questions: (1) within the existing statutory framework, what should the federal government do to better ensure meaningful tribal input into infrastructure-related reviews and decisions and the protection of tribal lands, resources, and treaty rights; and (2) should new legislation be proposed to Congress to alter that statutory framework and promote those goals....

In recent days, we have seen thousands of demonstrators come together peacefully, with support from scores of sovereign tribal governments, to exercise their First Amendment rights and to voice heartfelt concerns about the environment and historic, sacred sites. It is now incumbent on all of us to develop a path forward that serves the broadest public interest.
